It used to be called 'wallpaper', but now seems to be labeled 'background' when I go in from the startup screen. I always shut my computers right down - ie no power or even connection by wire - when I leave them. I know paranoid, but there you go.

Try a right click on a free space of the desk top. If you get a pop-up that allows setting the wallpaper, then use this.

Or click on the icon in the top right corner of your desktop for a pull-down box and click on the settings icon (screwdriver and wrench) in the bottom left corner of that pop-op
This should start a system setup window with (among others) an item for changing the wallpaper.
